+### `derived` — daily custom/derived data
+
+Derived data is daily-only v1 research data keyed by `symbol_id,date`, with one
+or more numeric value columns. It can come from user CSV/parquet files or Python
+plugins, and is written as a single parquet file at `derived/{name}.pq`.
+
+The validator normalizes `date` to the trading day, requires unique
+`symbol_id,date` keys, rejects duplicate columns, and rejects non-numeric value
+columns. Alpha computation consumes derived data through the existing
+`--feature-path` flag.
+
+```bash
+# Validate a user file without writing output.
+uv run python cli.py derived validate --input-path vendor_factor.csv
+
+# Ingest CSV/parquet into the canonical derived/ layout.
+uv run python cli.py derived ingest \
+    --input-path vendor_factor.csv \

+
+For compatibility, `feature list` and `feature compute` remain available and
+delegate to the same derived-data registry. Existing `features/*.pq` files are
+still valid `--feature-path` inputs when they satisfy the daily numeric contract.

+  custom universes available.
+- **Categorical derived data** — extend the numeric-only derived-data v1 contract
+  to support categorical inputs such as industry classifications. In this
+  project, "Level 2" means customized second-level research data produced by
+  users or plugins; it does not necessarily mean exchange order-book/L2 quote
+  feeds.
+- **Minute bar data** — continue extending the raw minute-bar and feature
+  workflow. The initial Baostock 5-minute download and daily feature plugin path
+  exist; intraday execution and replacing canonical daily bars remain out of
+  scope unless explicitly added later.
+- **Industry data** — add industry classification inputs for filtering,
+  grouping, exposure reporting, neutralization, or industry-aware portfolio
+  construction.

+# JoinQuant Comparison Plugin
+
+## Why a Plugin
+
+JoinQuant is an external execution and simulation reference. Keeping this code
+under `plugins/joinquant/` prevents vendor-specific assumptions from entering
+`pipeline/portfolio/`, where the internal reference simulator remains the
+canonical implementation.
+
+## What It Validates
+
+The comparison is for system correctness:
+
+- date alignment
+- internal to JoinQuant symbol mapping
+- target position generation
+- once-per-day open execution timing
+- lot rounding and filled shares
+- position carry
+- trading cost
+- PnL accounting
+- blocked trades from suspension, limit-up, and limit-down conditions
+
+## What It Does Not Validate
+
+It does not validate alpha quality, IC, IR, forecast skill, or whether the
+strategy is economically useful. Differences can be expected when JoinQuant
+uses different fee, slippage, cash, corporate-action, or internal rounding
+rules.
+
+## Historical Backtest Workflow
+
+```bash
+# 1. Build internal portfolio targets.
+uv run python cli.py portfolio build ...
+
+# 2. Export JoinQuant-compatible frozen targets.
+uv run python cli.py joinquant export-targets \
+  --positions-path portfolio/run1.pq \
+  --portfolio-name run1 \
+  --mode target_shares \
+  --execution-calendar-path data/daily_bars/<universe> \
+  --out-dir plugins_output/joinquant/targets
+
+# 3. Generate and copy the wrapper strategy and target files into JoinQuant.
+uv run python cli.py joinquant write-wrapper \
+  --portfolio-name run1 \
+  --mode target_shares \
+  --out-path plugins_output/joinquant/wrapper_strategy_run1.py
+
+# 4. Run the JoinQuant backtest or simulated trading job.
+# 5. Export JoinQuant fills, positions, and daily PnL to CSV.
+
+# 6. Ingest JoinQuant output.
+uv run python cli.py joinquant ingest \
+  --portfolio-name run1 \
+  --fills-csv path/to/jq_fills.csv \
+  --positions-csv path/to/jq_positions.csv \
+  --pnl-csv path/to/jq_pnl.csv
+
+# 7. Reconcile.
+uv run python cli.py joinquant reconcile \
+  --portfolio-name run1 \
+  --targets-dir plugins_output/joinquant/targets/run1 \
+  --our-fills-path fills/run1.pq \
+  --our-positions-path portfolio/run1.pq \
+  --our-pnl-path pnl/run1.pq \
+  --jq-fills-path plugins_output/joinquant/ingested/run1/fills.pq \
+  --jq-positions-path plugins_output/joinquant/ingested/run1/positions.pq \
+  --jq-pnl-path plugins_output/joinquant/ingested/run1/pnl.pq
+```
+
+## Forward-Testing Workflow
+
+After the T-1 close and after the data update:
+
+```bash
+uv run python cli.py portfolio build ...
+uv run python cli.py joinquant export-targets \
+  --positions-path portfolio/run1.pq \
+  --portfolio-name run1 \
+  --mode target_shares \
+  --execution-calendar-path data/daily_bars/<universe> \
+  --start-date T \
+  --end-date T
+```
+
+Before the T open, upload or expose the frozen target file to JoinQuant. During
+the T open, the JoinQuant wrapper reads that file and submits orders, while the
+internal simulator should run against the same frozen target. After T close or
+after JoinQuant results are available, ingest the JoinQuant CSV files and run
+`joinquant reconcile`.
+
+Forward target files must be frozen before execution. Do not regenerate a
+target file after observing open or close data for the same trading date. The
+exporter writes a snapshot JSON with a SHA-256 hash for this reason and refuses
+to overwrite existing target/snapshot files unless `--force` is passed.
+
+For comparisons against the internal simulator, pass
+`--execution-calendar-path` to `joinquant export-targets`. The positions file is
+dated by construction/signal date, while the simulator executes at the next
+available open. The calendar option shifts exported target files to that next
+trading date, so JoinQuant reads the same target on the same execution session.
+
+For JoinQuant 模拟盘, the browser automation has two operational phases:
+
+```bash
+# Before T open: upload frozen target(s), save strategy, and start/restart 模拟盘.
+uv run python cli.py joinquant write-browser-config \
+  --out-path /tmp/chinese-equity-quant-realdata/joinquant_sim_config.json \
+  --strategy-url "https://www.joinquant.com/<your 模拟盘 page>" \
+  --flow sim-trade
+
+uv run python cli.py joinquant run-browser-sim \
+  --manifest-path /tmp/chinese-equity-quant-realdata/joinquant_smoke_manifest.json \
+  --config-path /tmp/chinese-equity-quant-realdata/joinquant_sim_config.json \
+  --storage-state ~/.config/chinese-equity-quant/joinquant_storage_state.json \
+  --headed
+
+# After T close: download/export JoinQuant fills, positions, and pnl, then
+# ingest/reconcile. The same run-browser-sim command can do this if the config
+# includes download actions, otherwise use the ingest/reconcile commands.
+```
+
+The default simulated-trading template includes selectors for saving the
+strategy and clicking simulated-trading controls such as `模拟盘`, `模拟交易`,
+`启动`, and `重启`. These selectors are intentionally configurable because the
+JoinQuant web UI can differ by account and page version.
+
+## Target-Shares Mode
+
+`target_shares` is the default and preferred correctness mode. The exported
+`target_shares` field comes from the internal `position_shares` column produced
+by `portfolio build`, because the internal simulator executes that discretized
+integer book. The generated wrapper calls:
+
+```python
+order_target(jq_symbol, target_shares)
+```
+
+This mode makes filled shares, position carry, and blocked trades easiest to
+compare.
+
+## Target-Value Mode
+
+`target_value` mode exports `target_value` and `target_weight` from the
+portfolio file. The generated wrapper calls:
+
+```python
+order_target_value(jq_symbol, target_value)
+```
+
+This can be useful for portfolio-level comparisons, but JoinQuant may apply its
+own rounding, cash, and lot rules. Differences are often classified as
+`JOINQUANT_INTERNAL_ROUNDING`, `LOT_ROUNDING`, or `CASH_CONSTRAINT` depending
+on the observed output.
+
+## Symbol Mapping
+
+Internal symbols are converted as follows:
+
+```text
+sh600000 -> 600000.XSHG
+sh688001 -> 688001.XSHG
+sz000001 -> 000001.XSHE
+sz300001 -> 300001.XSHE
+```
+
+Reverse mapping is also supported. Invalid exchanges or unsupported A-share
+prefixes raise `ValueError` instead of silently guessing.
+
+## Wrapper Strategy Usage
+
+Generate a configured wrapper:
+
+```bash
+uv run python cli.py joinquant write-wrapper \
+  --portfolio-name run1 \
+  --mode target_shares \
+  --out-path plugins_output/joinquant/wrapper_strategy_run1.py
+```
+
+Copy the generated file and daily CSV target files into JoinQuant. The default
+loader uses JoinQuant `read_file`, which works for uploaded files. If your
+JoinQuant runtime allows HTTP or another storage backend, replace only
+`_read_target_file()` in the generated strategy.
+
+The wrapper is long-only by default:
+
+```python
+ALLOW_SHORT = False
+```
+
+Negative targets are clipped to zero and logged. Use `--allow-short` only if
+the target JoinQuant account supports the required shorting mechanics.
+
+## Ingesting JoinQuant Outputs
+
+The ingest command accepts permissive CSV column names and writes strict plugin
+schemas:

+Missing cost fields default to zero. Missing blocked status defaults to zero.

+## Reading Reconciliation Reports
+
+The reconcile command writes:
+
+```text
+plugins_output/joinquant/reconcile/{portfolio_name}/daily_reconcile.pq
+plugins_output/joinquant/reconcile/{portfolio_name}/summary.csv
+plugins_output/joinquant/reconcile/{portfolio_name}/summary.md
+```
+
+`daily_reconcile.pq` is per-symbol and includes target shares, internal filled
+shares, JoinQuant filled shares, realized positions, trade prices, costs, PnL,
+and a `diff_reason`. `summary.csv` is the daily portfolio-level view for gross
+exposure, net exposure, cash, total value, PnL, cumulative PnL, turnover, and
+cost.
+
+Difference reasons include:
+
+```text
+MATCH SYMBOL_MAPPING PRICE_MISMATCH LOT_ROUNDING SUSPENSION LIMIT_UP_BLOCK
+LIMIT_DOWN_BLOCK VOLUME_OR_LIQUIDITY COST_MODEL CASH_CONSTRAINT
+SHORT_NOT_SUPPORTED CORPORATE_ACTION JOINQUANT_INTERNAL_ROUNDING
+MISSING_IN_OUR_SYSTEM MISSING_IN_JOINQUANT UNKNOWN
+```
+
+Default tolerances are exact share matching, `1e-4` relative trade-price
+tolerance, and value tolerance `max(1 yuan, 1e-6 * booksize)`. PnL tolerance is
+configurable with `--pnl-tolerance`.
+
+## Minimal Example
+
+Create a 5-stock equal-weight or fixed-share test portfolio:
+
+```text
+sh600000, sz000001, sh600519, sz002594, sz300750
+```
+
+Build positions for a small date range, export `target_shares`, upload the CSV
+files and wrapper to JoinQuant, run the JoinQuant backtest, export fills,
+positions, and PnL, then run ingest and reconcile. Start with one or two days
+before expanding the sample.
+
+For the first one-stock long-only smoke test, the local side can be prepared in
+one command:
+
+```bash
+uv run python cli.py joinquant prepare-smoke \
+  --out-dir /tmp/chinese-equity-quant-realdata
+```
+
+The command downloads a tiny public daily-bar sample, builds a fixed-share
+`sh600000` long-only position file, simulates it internally, exports aligned
+JoinQuant target files, writes a configured wrapper strategy, and creates
+`joinquant_smoke_manifest.json` with all output paths.
+
+## Browser Backtest Automation
+
+JoinQuant's public `jqdatasdk` is a data SDK. It supports authenticated data
+calls such as `auth(username, password)` and `get_price(...)`, but cloud
+strategy upload, backtest execution, and result export are web-application
+workflows. The plugin therefore automates those remote steps through Playwright
+with a saved browser session.
+
+Install the optional browser runner in the uv environment:
+
+```bash
+uv sync --extra joinquant-browser
+uv run playwright install chromium
+```
+
+Save a reusable login state. This opens a browser; log in normally, including
+any CAPTCHA or 2FA, then press Enter in the terminal to save state:
+
+```bash
+uv run python cli.py joinquant browser-login \
+  --storage-state ~/.config/chinese-equity-quant/joinquant_storage_state.json
+```
+
+Create a selector/action config for a historical backtest:
+
+```bash
+uv run python cli.py joinquant write-browser-config \
+  --out-path /tmp/chinese-equity-quant-realdata/joinquant_browser_config.json \
+  --strategy-url "https://www.joinquant.com/<your strategy page>" \
+  --flow backtest
+```
+
+If selectors need tuning, capture the logged-in page:
+
+```bash
+uv run python cli.py joinquant browser-snapshot \
+  --url "https://www.joinquant.com/<your strategy page>" \
+  --out-dir /tmp/chinese-equity-quant-realdata/browser_snapshot
+```
+
+Then run the remote backtest automation:
+
+```bash
+uv run python cli.py joinquant run-browser-backtest \
+  --manifest-path /tmp/chinese-equity-quant-realdata/joinquant_smoke_manifest.json \
+  --config-path /tmp/chinese-equity-quant-realdata/joinquant_browser_config.json \
+  --storage-state ~/.config/chinese-equity-quant/joinquant_storage_state.json \
+  --headed
+```
+
+The config is declarative: actions can navigate, paste the generated wrapper,
+upload all target CSV files, fill dates, click run, wait for completion,
+download result CSVs, and take screenshots. When the configured downloads
+produce fills, positions, and PnL CSVs, the runner automatically calls
+`joinquant ingest` and `joinquant reconcile`.
+
+For forward testing / 模拟盘, create the config with `--flow sim-trade` and run:
+
+```bash
+uv run python cli.py joinquant run-browser-sim \
+  --manifest-path /tmp/chinese-equity-quant-realdata/joinquant_smoke_manifest.json \
+  --config-path /tmp/chinese-equity-quant-realdata/joinquant_sim_config.json \
+  --storage-state ~/.config/chinese-equity-quant/joinquant_storage_state.json \
+  --headed
+```
+
+Do not store raw JoinQuant passwords in this repository. The browser state file
+is created with `0600` permissions and should live under `~/.config`, outside
+the repo.
+
+## Recommended First Sanity Checks
+
+1. One liquid stock with a fixed target share count.
+2. A 10-stock equal-weight long-only portfolio.
+3. A forced suspension, limit-up, and limit-down sample.
+4. A short target in long-only mode to confirm `SHORT_NOT_SUPPORTED`.
+5. A 5-day reversal portfolio after the mechanical checks pass.
+
+## Known Limitations
+
+- JoinQuant internal execution details may differ from the reference simulator.
+- External file loading depends on the JoinQuant environment.
+- Short selling may not be supported.
+- Fee, tax, slippage, and minimum-fee models may differ.
+- Corporate actions may need special handling and should not be hidden.
+- The internal simulator does not currently emit execution price in
+  `FILL_COLUMNS`; price reconciliation uses explicit price columns if supplied.

+# JoinQuant Cost Model Findings
+
+Generated: 2026-07-06
+
+This report summarizes the JoinQuant trading-cost behavior observed from the
+browser-automated real-data backtests and compares it with the current internal
+simulator model. The JoinQuant cost formula below is inferred from rendered
+transaction tables and strategy logs for this account. Treat it as an observed
+platform default, not as a guaranteed external contract.
+
+## Runs Used
+
+### Longer Comparison Run
+
+- Portfolio: `jq_long_one_stock_long`
+- Window: `2024-01-11` to `2024-02-29`
+- Booksize: `1,000,000 CNY`
+- Instrument: `600000.XSHG`
+- Target: buy and hold `1,000` shares
+- JoinQuant rendered result: completed
+- Local total PnL: `546.22 CNY`
+- JoinQuant total PnL from positions tab: `575.00 CNY`
+- Difference: `28.78 CNY`, or `0.002878` percentage points on the book
+
+The first JoinQuant transaction was:
+
+| Date | Side | Shares | Price | Turnover | Fee |
+|---|---:|---:|---:|---:|---:|
+| `2024-01-11` | Buy | `1,000` | `6.57` | `6,570.00` | `5.00` |
+
+That trade hit a minimum fee. The local simulator charged `6.1415 CNY` because
+the smoke runner used a flat `10 bps` cash cost on adjusted-price turnover.
+
+### Cost Probe Run
+
+- Portfolio: `jq_cost_probe_buy_sell`
+- Window: `2024-01-11` to `2024-01-12`
+- Booksize: `1,000,000 CNY`
+- Instrument: `600000.XSHG`
+- Targets:
+  - `2024-01-11`: buy `100,000` shares
+  - `2024-01-12`: sell to `0` shares
+
+Observed JoinQuant transactions:
+
+| Date | Side | Shares | Price | Turnover | Fee | Implied Fee |
+|---|---:|---:|---:|---:|---:|---:|
+| `2024-01-11` | Buy | `100,000` | `6.57` | `657,000.00` | `197.10` | `3.0000 bps` |
+| `2024-01-12` | Sell | `-100,000` | `6.51` | `651,000.00` | `846.30` | `13.0000 bps` |
+
+The transaction-table numbers match this formula exactly:
+
+```text
+buy fee  = max(5 CNY, turnover * 0.0003)
+sell fee = max(5 CNY, turnover * 0.0003) + turnover * 0.001
+```
+
+In basis points:
+
+- Buy commission: `3 bps`
+- Sell commission: `3 bps`
+- Sell stamp tax: `10 bps`
+- Minimum commission: `5 CNY`
+
+No separate transfer fee was visible in this probe. If a separate transfer fee
+was present as an additional charge, the observed fees would not match the
+formula above exactly. It may still be folded into JoinQuant's displayed
+commission field, so this finding should be read as "not separately observable"
+rather than "impossible".
+
+No slippage was visible. The wrapper submitted open-time market orders with
+`run_daily(..., time="open")`, and JoinQuant filled them at the displayed open
+prices.
+
+## Evidence From Strategy Logs
+
+The JoinQuant order log for the cost probe showed:
+
+```text
+2024-01-11 ... trade price: 6.57, amount:100000, commission: 197.1
+2024-01-12 ... trade price: 6.51, amount:100000, commission: 846.3
+```
+
+The normal transaction tab showed the same fee values. However, the generated
+wrapper's `JOINQUANT_FILL` log records had `trade_cost: 0.0`, even for those
+same fills. That means `get_trades()` did not expose the usable commission
+value through the field the wrapper currently reads.
+
+For reconciliation, use the transaction table or JoinQuant order logs for fee
+details. Do not rely on the wrapper's current `JOINQUANT_FILL.trade_cost`.
+
+## Difference From The Internal Simulator
+
+The current internal simulator cost model is
+`SimpleProportionalCostModel` in `pipeline/portfolio/costs.py`:
+
+```text
+trade_cost = abs(traded_shares * execution_price)
+             * (cost_bps + slippage_bps) / 10000
+```
+
+The smoke runner used:
+
+- `cost_bps = 5`
+- `slippage_bps = 5`
+- combined one-way cash cost: `10 bps`
+
+Important differences:
+
+- The internal simulator uses the same rate for buys and sells.
+- It has no minimum commission.
+- It has no sell-only stamp tax.
+- Slippage is modeled as an extra cash cost.
+- JoinQuant did not show slippage in the observed open-time fills.
+- The local smoke download used `adjust="qfq"`, while the JoinQuant wrapper set
+  `set_option("use_real_price", True)`. That price-scale mismatch also affects
+  PnL and cost comparisons.
+
+## Practical Implications
+
+For a buy-only smoke test, JoinQuant may charge less than the local model when
+the trade is large enough for `3 bps` to apply, but it may charge more on small
+orders because of the `5 CNY` minimum.
+
+For any test with sells, JoinQuant's default sell fee is materially higher than
+the current local flat model because of the inferred `10 bps` stamp tax.
+
+The earlier 30-day buy-and-hold discrepancy was small because only one buy was
+executed. A rebalancing strategy with many sells will show a larger cost-model
+difference unless the local simulator is configured to match JoinQuant.
+
+## Recommended Follow-Ups
+
+1. Add a JoinQuant-style cost model to the internal simulator:
+
+```text
+commission = max(min_commission, turnover * commission_bps / 10000)
+stamp_tax  = turnover * sell_stamp_tax_bps / 10000 for sells only
+trade_cost = commission + stamp_tax
+```
+
+2. Add a CLI option or preset for `portfolio simulate`, for example
+`--cost-model joinquant-stock`.
+
+3. Update JoinQuant reconciliation to parse fee values from the transaction
+table or order logs when CSV exports are unavailable.
+
+4. Run a second local-vs-JoinQuant comparison with:
+
+- raw or real-price local bars, not adjusted-price bars
+- JoinQuant-style costs
+- slippage disabled locally
+
+That test should isolate remaining differences to data alignment, price source,
+rounding, and JoinQuant internal execution behavior.
+

+# Minute Bar Data Notes
+
+The minute-bar path downloads raw Baostock intraday bars and stores them as a
+Hive-partitioned dataset:
+
+```bash
+uv run python cli.py data download-minute \
+    --universe sh600000 \
+    --start-date 2024-01-02 --end-date 2024-01-05 \
+    --frequency 5
+```
+
+The default layout is:
+
+```text
+data/minute_bars/{universe}/frequency=5m/month=YYYY-MM/*.pq
+```
+
+Derived-data plugins can aggregate those bars to daily `symbol_id,date` numeric
+files, for example:
+
+```bash
+uv run python cli.py derived compute \
+    --minute-path data/minute_bars/sh600000 \
+    --daily-path data/daily_bars/sh600000 \
+    --derived-type minute_daily_summary \
+    --derived-name minute_summary
+```
+
+The legacy `feature compute` command delegates to the same derived-data
+registry and remains available for existing scripts.
+
+## Daily vs Minute Reconciliation
+
+Baostock's daily raw bars and 5-minute raw bars are close, but they should not
+be treated as perfectly reconstructible from each other.
+
+When checking consistency, compare daily raw bars (`data download --adjust none`)
+against minute bars on the same raw price scale. The minute aggregation should
+use:
+
+- `open`: first minute open
+- `high`: max minute high
+- `low`: min minute low
+- `close`: last minute close
+- `volume`: sum minute volume
+- `amount`: sum minute amount
+- `vwap`: `sum(amount) / sum(volume)`
+
+In a sanity check for `sh600000` from `2024-01-02` through `2024-01-05`, Baostock
+returned 4 daily rows and 192 5-minute bars, exactly 48 bars per day. Open, low,
+and close matched daily exactly on all 4 days. High matched on 3 of 4 days; on
+`2024-01-04`, the daily high was `6.67` while the max 5-minute high was `6.66`.
+Minute-summed volume and amount were higher than daily by roughly `0.16%` to
+`1.23%`. VWAP remained very close, with max relative difference around
+`0.0043%`.
+
+This appears to be a source-level Baostock reconciliation caveat, not a parser
+or ordering issue: the minute bars covered the regular `09:35:00` through
+`15:00:00` range and sorted correctly by timestamp.
+
+Practical guidance:
+
+- Use tolerance-based daily-vs-minute checks; do not require exact equality for
+  high, volume, or amount.
+- Expect open/close alignment to be a stronger sanity check than exact volume
+  reconstruction.
+- Use minute-derived values as separate daily features, not as replacements for
+  the canonical daily bar dataset unless a strategy explicitly wants that
+  source convention.

+# JoinQuant Comparison Plugin
+
+This plugin exports frozen targets from the internal A-share research pipeline,
+drives a standalone JoinQuant wrapper strategy, ingests JoinQuant output files,
+and reconciles them against the internal reference simulator.
+
+The plugin validates system mechanics, not alpha quality:
+
+- date alignment
+- symbol mapping
+- target position generation
+- open execution timing
+- lot rounding and filled shares
+- position carry
+- trading cost and PnL accounting
+- blocked trades from suspension and price limits

+
+`target_shares` is the default and uses the built integer `position_shares`
+from `portfolio build`, matching what the internal simulator executes.
+For strict simulator-vs-JoinQuant comparison, pass `--execution-calendar-path`
+so position dates are shifted to the next session open, matching the internal
+simulator's next-open convention.
+
+`prepare-smoke` automates the local side of the first sanity check: tiny real
+data download, one-stock long-only position file, internal simulation, aligned
+target export, wrapper generation, and a manifest with expected JoinQuant CSV
+export paths.
+
+`run-browser-backtest` automates the remote JoinQuant web run through
+Playwright. It reuses a saved browser login state, executes the configured UI
+actions, downloads JoinQuant CSVs when configured, and runs ingest/reconcile
+automatically once all three CSVs are present.
+
+`run-browser-sim` is the forward-test / 模拟盘 equivalent. Use a `--flow
+sim-trade` config to upload the frozen next-session target file, save the
+strategy, and start or restart the JoinQuant simulated-trading job. After close,
+run it again with download actions or use `ingest` / `reconcile` directly on
+exported CSVs.
